Could Someone Identify These Grips, Please?

[Luke]

Picked these up at a recent gun show. They are made of a hard, brittle, brown plastic material. They fit better than any repros I have seen,in fact, as well as the Nill wooden grips. Would like to know what they are.

Thanks for your comments.

Luke
